Save an Image in a MySQL database

I am trying to save an image in a MySQL database. This is what I have done so far; I have created a table with one of the variables called
photo blob, this is what you use to save an image right?
When I write the image to the database after getting connected to it is where I am stuck, so far I can save Ints, Strings and Enum s values but I do not know how to convert my image into a Blob and save the blob. I have been doing some light reading and I am guessing I have to convert the image into a Stream of some sort. What type of stream I do not know. This is the java command I have to save the Blob but do not know what to use as the variable for the Blob.
prst.setBlob(5, "??????");As you can tell by the ????? marks, I do not know how to convert my image into the proper data type(whatever the data type is?) to save the contents into the database.
If somebody has the exact copy of the all the java coded steps that is needed to save an image as a Blob into a prepared database, that would be extremelu helpful to me.
Thank-you.

The answer has to be quite simple. If you do not have
the answer please do not reply.Unfortunately it's not simple. This is one of my betes noire about the java libaries. The Blob stuff has gaping holes in it. There's no method, anywhere, to create a new Blob or Clob (also the design of the Blob and Clob interfaces tends to miss the point).
The ways arround this, there being no legitimate approach, vary with the database provider.
If the program an the server are running on the same machine (or files can be shared through NFS or the like) you can try the "LOAD_FILE" function.
With some databases I believe setBinaryStream instead of setBlob works, but I'm not sure the mySql driver is that smart.

Upload images to a MySQL database (PHP)?

Ok so i don't get any error but is not doing anything to my database, any suggestions?
<body>
<form action="image.php" method="POST" enctype="multipart/form-data">
File:
    <input type="file" name="image" />
    <input type="submit" value="Upload"/>
</form>
<?php
//Conect to database
$mydatabase = mysql_pconnect($hostname_mydatabase, $username_mydatabase, $password_mydatabase) or trigger_error(mysql_error(),E_USER_ERROR);
mysql_select_db("database")or die (mysql_error());
//file properties
$file = $_FILES['image']['tmp_name'];
if (!isset($file))
          echo"PLease select a file";
else
$image=addslashes(file_get_contents($_FILES['image']['tmp_name']));
$image_name=addslashes($_FILES['image']['name']);
$image_size=getimagesize($_FILES['image']['tmp_name']);
if($image_size==FALSE)
          echo "That's not an image.";
else
          if ($insert = mysql_query("INSERT INTO table VALUES ('$image_name', '$image')"))
          echo "Problem uploading image.";
          else
?>
</body>

Why do you want the binary value of the image?
Just save the image name as you are and then move the uploaded file to the proper folder on your server.

Saving image in MySQL database

Best groupmember,
I want to save my images in a MySQL database. After storing that in the database I want to be able to present it using a servlet. Something like this (show image with id=4 from the database):
<img src="/servlet/image?id=4">
Would be happy to be guided to example code or tutorials about how to store images in a MySQL database using Java.
-- Best of Times
Peter Lauri

Ok for storing images you'll have to use the type BLOB (=Binary Large Object) for the rest i would suggest that you take a look at the jdbc-documentation....
this might help... :p

please help me.......
Thanks in Advance.

thanks for your help,
i had also tried this application by taking help from javazoom.upload, using multipart request,
but that is was working fine,but the problem with that was i not only hav to upload a file in the same page i also have to save other textbox value (parameters).
i have used 2-3 solutions to upload but the main prblm coming in my way is to save other information apart from uploaded file.
with that MultipartRequest i'm unable to save all those information to mysql database.
thats why i used this way.
Note give me hint so that solution can work on both Explorer.
one more thing please tell me ,will this work on remote server ,as our site is hosted from other place ,we do't hav permission to access (in case of absolute path).
please help me out............where i'm going wrong.
thankx

Saving images in a mysql db?

Hi you all,
I have a question.
I'm working on a school project. And I was wondering if it is possible to save an image to a MySQL db with java.
I would like to save an specified image to the database, but I'm also wondering is I could display the image from the database again (I prefere that there is no temp file created).
(I have done this before with PHP)
Does anyone has ideas or sample codes for me?
Please hurry, I have only short time to finish the project.
With Kind Regards,
Franck Nijhof
(ps sorry my bad english)

I know that file in system is better. But in out project we must be saving a binary file in the database. A image is not that big and can be used usefull.
So I like to do an image instead of an big program.
(BTW I need it anyway, we need to build the program multiuser with network, this mean one is loading the image and everybody need to get it if they want to)
Hopefully some can help!
With kind regards,
Franck Nijhof

Saving an Image to an Oracle Database over the Internet

I would like to know how to transfer an image over the Internet and save that image to an Oracle Database. That is I am trying to make it so that a user can connect to the Internet and select an image file form their PC in TIFF, JPEG, or some other format. Next, I would like to save this image to an Oracle 7.3.4 Database in a LongRaw data type. This image will need to be save into a certain record in a table that I created. In the next few months we will be upgrading to Oracle 8 that uses Blob data type. Any one who knows how this can be done, please let me know.

Yes, that's right. Here is the pertinent code:
In the flax app:
private function captureImg(imgEnc:IImageEncoder):void {
var ohSnap:ImageSnapshot;ohSnap = ImageSnapshot.captureImage(img, 0, imgEnc);
textArea.text = ImageSnapshot.encodeImageAsBase64(ohSnap);
InsertImage(textArea.text);
In the HTTP service AS module:
private
function InsertImage(sImageCoded:String):void { var sQry:String;sQry =
"INSERT INTO image (lImageId, blbBitMap, txtImage, lRecipeId) " sQry +=
"VALUES(0, '" +sImageCoded +"', 'text', 23)"
//Alert.show(sQry);mysqlQuery(sQry,
"InsertImage");}
As mentioned previously, an HTTPrequest error is generated although I can enter
the string into the blob manually in MySQL.

Point me in the right direction: want to resize image & store in mysql db

I finally accomplished one of my tasks! Which was trying to upload a jpeg image into my mysql database, and then display it in a jsp page via a servlet. I extend my thanks to the java forums greatly:)
Now my next task I find is going to be trickier to accomplish, because I do not have enough experience working with images.
I would like to make my first task above more efficient.
When the user selects a jpeg file to send, I want to check the size of the image and resize it as well, before finally storing it in my Mysql database.
I do not want to lose the resolution, nor do I want it to look distorted after it is resized. I want to keep the same proportions as the original image (I hope that proportion is the proper term). After the image is stored successfully, it will be read out of the database and displayed within a jsp page via a servlet.
After poking around in the forums, I realized I need to get down the basics with regards to getting the properties of an image and trying to resize it. It doesn't look like it will be an easy task.
Does anyone know of any sites that provide a good, easy to understand tutorial? Or are there any books you would recommend I read? What Java classes should I be looking into to accomplish my task?
There are so many far more experienced programmers out there among the forums, that when I look at their code, I'm lost. I just want to understand this process better, by taking it one step at a time.
Any help is appreciated, as always:)
Thank You,
Love2Java

Load image with ImageIO
Call getWidth() and getHeight()
Create a BufferedImage with width and height scaled accordingly
Get the image's Graphics2D object
Call drawImage(), passing an AffineTransform to scale accordingly
Output the image via ImageIO
That should be it - you just need to read the APIs for the classes I've mentioned, and tack on whatever input/output streams you need at either end (see the java.io package).
The only thing is:
I do not want to lose the resolution
Not totally sure what you mean: if you're scaling the image down to a thumbnail then by definition you're losing resolution. If you mean you want to keep the DPI resolution metadata in the image then you'll have to Google for it, the information is there but it hasn't remained in my head :o)
But then I can't imagine why you'd need DPI metadata in a thumbnail anyway, so you can probably ignore it.

i need ur help,we hav online site .Please don't use these juvenile abbreviations. It's impolite when you're asking for assistance not to make the effort to spell out all of the words. Moreover in a forum with an international readership the use of standard English will reduce the possibility of confusion.
I presume that your file upload is being placed in a different directory from that which you were expecting. I would suggest logging all paths (specifically filename) to see if this is an unexpected value.
Please explain further what you mean by "local" - is this a stand-alone application, or merely running a copy of the server on your local machine and doing the transfer (via the browser) to that? Are there any other differences such as the browser used?

Uploading images for a mySQL / PHP database

Hopefully this can be done - I'm working on a site that uses
a simple mySQL database, where the records include an image.
I have the form to add records, including the field
containing the file name - but is it also possible to upload the
actual file using the same form to their folder, or does that need
to be done separately using FTP software?
The idea is for my client to be able to as easily as possible
add / delete / edit records himself, so clearly getting the actual
images uploaded at the same point he adds records to the database
would be great if that's possible.
Cheers,
Iain

The PHP.NET site really covers it in considerable detail.

Storing images in a database is generally not a good idea. Apart from bloating your database and increasing the risk of table fragmentation when images are updated or deleted, you cannot display an image directly from a database. However, if you want to do it, you will find instructions here: http://cookbooks.adobe.com/post_Upload_images_to_a_MySQL_database__PHP_-16609.html.
The more common (and efficient) approach is to use the database to store details of the image, such as filename and caption. Then upload the image to your website's file system.
I give step-by-step instructions how to do this in my book, "Adobe Dreamweaver CS5 with PHP: Training from the Source", but if you have reasonable skill at using PHP, you can learn how to handle file uploads from the PHP Manual at http://docs.php.net/manual/en/features.file-upload.php.

Awt.image writing to mysql

I am trying to write an Image datatype to a mysql database. The problem is that all the tutorials and books tell you how to do this directly from a file then get a filestream etc etc.
I am working on the server side of a system so the image wont have come from that system. Therefore i can not give a filename or a path. HOW to i get the image to write to the database in its current state?
thanks

Is there anyway to get the ImageIcon or Image
datatypes into a form where they could be written to
the database? Is there a way even to convert back
from
Image image; to File file?Assuming that you are using javax.swing.ImageIcon:
This class is serializable:
http://java.sun.com/j2se/1.5.0/docs/api/javax/swing/ImageIcon.html
http://java.sun.com/j2se/1.5.0/docs/api/java/io/Serializable.html
http://java.sun.com/docs/books/tutorial/essential/io/serialization.html
Therefore, you could serilize the object which turns it into a stream of bytes and save it to the database using what I mentioned in my previous post and unserialize it to get it back to its original state. There are some possible issues because serializing objects in not really intended for long term storage (versions change, etc.).
There is also XML object storage - you should find an article about it if you search this site.

How to get data into the mySQL database?

First some background.
I have a website that has outgrown its designed dimensions and is a huge burden to maintain. See PPBM5 Benchmark
There is a lot of maintenance work involved, so I'm investigating a PHP/MySQL approach to easen the burden and to add functionality to the site. With the current Excel based structure and over 420 entries, it is cumbersome for me to maintain, but also for users to find what they need.
A MySQL based dynamic structure is a lot easier and offers vastly more selection capabilities, like selecting only records that meet specific criteria.
Data submission is done with a form, that contains most of the relevant data, but the drawack is that people submitting their data are often not technically inclined, give wrong answers due to a lack of understanding or making typo's. The test results are attached in one or two separate .txt files, but often they have not read the instructions correctly or did something wrong, so these attached .txt files can not be trusted automatically, they have to be checked before inclusion.
These were my initial thoughts:
1. Data collection:
To avoid spending all our energy and time on correcting typo's, getting missing data, correcting errors, I am investigating the use of CPU-Z in Ghost mode to create a .txt or .html file that contains all relevant hardware info we need and even more. It gives all the info we currently have, but adds data like number of memory sticks, DDR timings, stock clock speed and BCLK setting, video card info and VRAM size, etc.
To see what I mean, run CPU-Z, go to the About tab and press the Save Report button and look at the results.
This can all be done without user intervention in an automatic way, but maybe I need to add an Auto-It file to the test to make it all run as desired.
If this works and I'm able to extract the relevant data from the created file and can insert it into the database, we may be in business for the next version of PPBM5.5 or PPBM6. It does require a modification to the instructions, making them a lot easier, because there is less data to fill out.
2. Data submission:
The submission form can be simplified if the CPU-Z data can be used. We have to create an automatic way to attach the created .html file from CPU-Z to the submission form and we have to streamline the Output.txt and Output-MPE.txt files to be more easily included in the 'form.lib.php' file. It currently is manual labor and very time consuming.
3. Adding to Database:
I have to find a way to create database records from the Gmail forms I receive. All incoming mail messages need to be checked on relevancy and if relevant, need to be added automatically to the database and then offered for approval before final inclusion in the database. Data included in the database will then include submission date and time, Email address, IP address used, plus links to the files submitted and available on the website.
4. Publication of the database:
After approval of new records from step 3, all updates will be automatically applied to the database and accessible for users. I do not yet intend to introduce a user account , requesting login before all functionality is accessible. Too much trouble and administration.
Queries should be possible on things like CPU (check box), so include 17-920, i7-930, i7-950 but exclude i7-980X and i7-990X, Size of memory (check box), Overclocked (boolean, yes, no), SSD as OS disk, and similar options.
The biggest problem is to keep the color grading and statistical indicators (Top, D9, Q3, Med, Q1 and D1) intact on dynamically generated queries. Say you make a query which results in 20 observations, this should show the related colors and legends. Next query results in 48 observations and of course the color grading and legends do need to reflect that. Question in my mind, does the RPI remain constant, independent of the query or does that need to be recalculated on the basis of the query?
Next thing is to allow a user to select a specific observation and by simply clicking on it be shown, in a separate window (detail page) or accordion, all the CPU-Z related information about the hardware.
The graphs, Top-20 and MPE Gains, need to be dynamically adjusted, based on the query used.
5. Ideally, external links:
In an ideal situation, one could link the CPU-Z data to external price databases, looking up current prices for CPU, memory, video card, disks, raid controller, etc. to get instant BFTB charts, based on the query made. But that is the next step.
Situation now:
I have a MySQL database that is easily updated with the new submissions. Simply create a .CSV flie from the submitted forms and import that into the database. The bulk of the initial work is done.Lots remain to be done as you can see above, but that is for a later time.
Question:
I have this table, that needs to be filled with data in the submitted and attached files. Mr. X submitted his data and can be uniquely identified by his "Ref_ID". He attached one or two files in .TXT format with the relevant test data. These files are stored on the server with a concatenated name:
"Ref_ID","-","filename"
Say his Ref-ID is: 20110204-6cf5 and his submitted file is called: Output(99).txt then the file can be found on the server as
20110204-6cf5-Output(99).txt
I need to be able to open that comma delimited file, the contents may look like this: "439","1036","819","531" and insert these contents into the relevant record and fields.
Graphically,
is what I want to achieve.
This being my first exposure to PHP/MySQL, you can imagine I'm not clear on how to go from here.
Added complication is that I actually have 5 numbers to insert per record and two calculated fields, Total Score and RPI should be calculated fields. Haven't yet figured out how to handle calculated fields, maybe only in the PHP/HTML code and not in the database.
I hope someone can help me.

You do have a very complex looking site and may need several tables in mysql to handle all that data. If you knew to phpmysql I would suggest taking a look at this tutorial it will help get you started in understanding how to $_GET info from a database and also how to $_POST data to a database. I am no expert just learning myself and I found this very helpful. This is the link http://www.adobe.com/devnet/dreamweaver/articles/first_dynamic_site_pt1.html
There are also many tutorials on Youtube to help build a CMS Content Management Site I would suggest the following: -
http://www.youtube.com/user/phpacademy
http://www.youtube.com/user/betterphp
http://www.youtube.com/user/flashbuilding
And many more on my channel here

CMS's are easier to maintain, add edit and delete content.
I have also recently bought a Book by David Powers Training from the Source very helpful.
Anyway hope you get it sorted.
